Applies to: SQL Server 2016 (13.x) and later Azure SQL Database Azure SQL Managed Instance

Enables unforcing a previously forced plan for a particular query in the Query Store.

Transact-SQL syntax conventions

Syntax

sp_query_store_unforce_plan
    [ @query_id = ] query_id ,
    [ @plan_id = ] plan_id ,
    [ @force_plan_scope = ] 'replica_group_id'
[ ; ]

Arguments

[ @query_id = ] query_id

The ID of the query. @query_id is bigint, with no default.

[ @plan_id = ] plan_id

The ID of the query plan that will no longer be enforced. @plan_id is bigint, with no default.

[ @force_plan_scope = ] 'replica_group_id'

You can force and unforce plans on a secondary replica when Query Store for secondary replicas is enabled. Execute sp_query_store_force_plan and sp_query_store_unforce_plan on the secondary replica. The optional @force_plan_scope argument defaults only to the local replica, but you can optionally specify a replica_group_id referencing sys.query_store_plan_forcing_locations.

Return code values

0 (success) or 1 (failure).

Permissions

Requires the ALTER permission on the database.

Examples

The following example returns information about the queries in the Query Store.

SELECT txt.query_text_id,
    txt.query_sql_text,
    pl.plan_id,
    qry.*
FROM sys.query_store_plan AS pl
INNER JOIN sys.query_store_query AS qry
    ON pl.query_id = qry.query_id
INNER JOIN sys.query_store_query_text AS txt
    ON qry.query_text_id = txt.query_text_id;

After you identify the query_id and plan_id that you want to unforce, use the following example to unforce the plan.

EXEC sp_query_store_unforce_plan 3, 3;
